Overview

BigQuery is Google's fully managed, NoOps, low cost analytics database. With BigQuery you can query terabytes and terabytes of data without having any infrastructure to manage or needing a database administrator. BigQuery uses SQL and can take advantage of the pay-as-you-go model. BigQuery allows you to focus on analyzing data to find meaningful insights.

The dataset you'll use is an ecommerce dataset that has millions of Google Analytics records for the Google Merchandise Store loaded into BigQuery. You have a copy of that dataset for this lab and will explore the available fields and row for insights.

This lab focuses on how to create new reporting tables using SQL JOINS and UNIONs.

What you'll do

In this lab, you learn how to perform these tasks:

Explore new ecommerce data on sentiment analysis

Join together datasets and create new tables

Append historical data with unions and table wildcards

Setup and requirements

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Cloud resources will be made available to you.

This Qwiklabs hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access the Google Cloud Platform for the duration of the lab.

What you need

To complete this lab, you need:

Access to a standard internet browser (Chrome browser recommended).

Time to complete the lab.

Note: If you already have your own personal GCP account or project, do not use it for this lab.

How to start your lab and sign in to the Console

Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method.
On the left is a panel populated with the temporary credentials that you must use for this lab.

Copy the username, and then click Open Google Console.
The lab spins up resources, and then opens another tab that shows the Choose an account page.

Tip: Open the tabs in separate windows, side-by-side.

On the Choose an account page, click Use Another Account.

The Sign in page opens. Paste the username that you copied from the Connection Details panel. Then copy and paste the password.

Important: You must use the credentials from the Connection Details panel. Do not use your Qwiklabs credentials. If you have your own GCP account, do not use it for this lab (avoids incurring charges).

Click through the subsequent pages:

Accept the terms and conditions.

Do not add recovery options or two-factor authentication (because this is a temporary account).

Do not sign up for free trials.

After a few moments, the GCP console opens in this tab.

Note: You can view the menu with a list of GCP Products and Services by clicking the Navigation menu at the top-left, next to “Google Cloud Platform”.
